STOPPER FOR BOTTLES OR JARS.

SPECIFICATION forming part of Letters Patent N o. 636,801, dated November 14, 1899. Application filed March 28, 1898. Serial No. 675.480. (No model.)

closed by a sort of valve forming a solid piece Y with the stopper, andthe object of this invention is to provide means for securing the outlet-valve as Well as the bottle-stopper by means of the same'device to the mouth of the bottle or jar. I attain this object by means of the mechanism particularly described hereinafter with reference to the accompanying drawings, in which- Figure lis a vertical section of my improved stopper as affixed to the mou th of an ordinary bottle, showing the outlet-valve in closed po-V sition; Fig. 2, a side elevation of the same; Fig. 3, a vertical section at right angles to Fig. l, but showing the position of parts in the state when the outlet-valve is open; and Fig. 4, a top view of Fig. 2.

Similar letters refer to similar part-s throughont the several views.

The outlet-valve b, forming part of the bot' tlc-stopper a, in the position illustrated by Figs. l and 2, is pressed from below against the elastic tightening ring or seat e, received in the mouth of the bottle or jar, not only by the pressure of the gas within the latter, but also by the lateral bars f, which engage within suitable recesses under the projection or shoulder g at the upper end of the stopper, whereb y an absolutely tight closure of the bottle or jar is effected. In this position of the stopper the bow f provided for connecting the-lateral bars f, b ears v against another projection or shoulder a of the stopper a in such a manner that a lifting of the latter on increased pressure of the gas Within the receptacle is prevented. In this position the stopper acts as an ordinary bottle-stopper outwardly connected to the mouth of the receptacle by means of the lever e `and the pivots Z. The lever e, by means of which the lateral rods f are pushed on theupward motion of the lever against the projection g, is at the position of rest and secured in this position on the one hand thereby, and the pivots Z of the lateral rods have passed the line ofpressure between the Working point and the fulcrum of the lever e, on the other hand,'by the springaction of the latter. By this means an accidental opening of the bottle-stopper is entirely prevented.

In unseating the'valve h for the purpose of giving free egress to the contents of the bottle or jar the lever e is turned from the position shown in Figs. l and 2 to the position shown in Fig. 3, during `which movement the valve l) remains on its seat so long as the rodsfslide in the slots or notches a2 in the stopper a, and it is only after said rods reach the lower end of said notches, at which time the lever e will be at a convenient angle relatively to the neck of the bottle for manipulation, and upon further pressure on said lever the stopper a'is forced inwardly, thereby unseating valve b and opening theA Huid-passage in the stopper a.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination with a bottle having` two elastic seats in its discharge-passage, of

a combined stopper and valve seated respectively on said seats, said stopper having a Huid-passage in communication with lateral passages formed in a throat or contracted portion intermediate of the stopper and valve, and means operated from without the bottle {f or shifting the stopper to unseat and seat the valve, for the purpose set forth.

2. The combination with a bottle having ,two elastic seats in its discharge-passage, of

va Acombined stopper and valve seated respectively on said seats, said stopper having a fluid-passage in communication with lateral passages formed in a throat or contracted portion intermediate of the stopper and valve, and means operated from without the bottle for shifting the stopper to unseat and seat the valve and lock the latter to its seat, for the purpose set forth. 'l

3. The combination with a bottle-neck and a ring-val ve seat therein, of a stopper'on one side of said seat and a plug-valve on the other connected to said stopper, a central opening through the stopper communicating with the interior of the bottle between the valve and the stopper, and wire lever mechanism for exerting an outward pressure t0 hold the valve seated, substantially as and for the purpose set forth.

4. In a bottle, the combination with astopper provided with notches and a bead, of a lever mechanism comprising a bail provided with eyes pivoted at the neck of the bottle and adapted to take under the bead and support the stopper when lifted, wire side barsf having their lower ends pivoted in the eyes of the bail and upper ends formed into pins, and a yoke connecting said pins, said pins adapted to exert an outward pressure on the stopper, substantially as set forth.

5. In a bottle, the combination with a stopper provided with two beads and notches, of a lever mechanism comprising a bail pivoted at the neck of the bottle and provided with eyes, said bail adapted to take under one of the beads, and side bars having their lower ends pivoted in the eyes, and upper ends formed into pins taking into the notches of the stopper, and a yoke connecting said pins and taking on the second bead, substantially as set forth.

6. Thecombinationwithabottle-neckanda ring-valve seat therein, of a stopper provided with beads and notches on one side of said seat and a plug-valve on the other and connectcd to said stopper, a central opening in said stopper communicating with the interior of the bottle between the stopper and valve, a bail provided with eyes pivoted at the neck of the bottle and adapted to prevent the stopper from being forced in and side bars pivoted in the eyes and taking into the notches of the stopper adapted to prevent the stopper from being forced out, substantially as set forth. .l
